Patent Claims
11 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The computer-implemented method of claim 1, wherein the generating the difference feature map comprises calculating a difference between first values corresponding to first pixels of the first frame and second values corresponding to second pixels of the second frame.

3

3. The computer-implemented method of claim 2, wherein the first values and the second values comprise Red Green Blue (RGB) values.

6

6. The computer-implemented method of claim 1, wherein the detecting the first object comprises regularizing, by the spatial attention layer, an output of the convolutional neural network.

7

7. The computer-implemented method of claim 1, wherein the spatial attention layer comprises a calculation of a difference between a weighted output of the convolutional neural network and values of the difference feature map.

8

8. The computer-implemented method of claim 1, wherein the first resolution is (7680×4320) pixels and the second resolution is (680×480) pixels.

10

10. The system of claim 9, wherein the generating the difference feature map comprises calculating a difference between first values corresponding to first pixels of the first frame and second values corresponding to second pixels of the second frame.

11

11. The system of claim 10, wherein the first values and the second values comprise Red Green Blue (RGB) values.

14

14. The system of claim 9, wherein the detecting the first object comprises regularizing, by the spatial attention layer, an output of the convolutional neural network.

15

15. The system of claim 9, wherein the spatial attention layer comprises a calculation of a difference between a weighted output of the convolutional neural network and values of the difference feature map.

17

17. The computer program product of claim 16, wherein the generating the difference feature map comprises calculating a difference between first values corresponding to first pixels of the first frame and second values corresponding to second pixels of the second frame.

18

18. The computer program product of claim 17, wherein the first values and the second values comprise Red Green Blue (RGB) values.
